If I was going to get one off fleabay aren’t I at risk of getting a dud one?
Also it would need reprogramming for the immobiliser, have the odometer / clock set to correct mileage, keys synchronised (im sure there are other things too, please can you confirm what these might be?)
I know of other software that can help me get the PIN code or SKC? But not sure if you need official / licensed to do this? Would hate to brick my ecu using something illegitimate. Is this a possible outcome Crasher?
It is a risk buying a used one but it has worked for us a number of times, there is even a VAG protocol for doing it. Unless you have it modified to get ride of the old cars VIN and mileage plus have the immobiliser deleted than it will have to be coded in using ODIS so the dealer or a specialist like me who has signed up for ODIS using the GEKO security system. The trouble with a new ECU is the cost, a new one for your car would be part number 03C 997 056 M and costs £1122.80. It is a so called “Vehicle Intelligent Part” and so has to be special ordered from a VW dealer (or TPS if you have an account) and has to come from Germany and is non-returnable. Trying to extract the PIN using CAN Commander is fraught with stolen software, you can't just ring them up for tec help! The SKC is no longer used, it is all done invisible on line to Der Fatherland, the grease monkey doing the job does not see anything useful any more.
Thanks once again for this information....
Still going for the overlay harness at the moment....then will get ECU checked out....
I did try a new (but non-OEM part) throttle body but as explained at the beginning of thread and it made no difference.....chucked the same code....would a NEW OEM / authentic part 03C 133 062 A make any difference even if I have tried a NEW aftermarket part?
Did try a used / second OEM part and still made difference either (but could have the same issue....)
Just trying to track down the correct terminal for the ECU pins.....I've found the correct terminal for the 1.0mm CSA wires.....just can't track down the correct 0.35mm CSA terminal.....looks <1mm in cross section but I haven't measured the ECU pin....just by eye this...
UPDATE....overlay harness between ECU and throttle body installed and NO MORE CODES for throttle body.....17580, 17579 have not returned which hopefully means the issue is resolved.
Just need to carefully route the new wiring to avoid any future issues and shorten its length as I have made it far too long.....
Appreciate your support Crasher on this one.
Will go on a spirited long drive and hopefully no codes will return.
Fingers crossed we can consider this solved.
